ROIC calculation:(annualized current quarter segment return)/(average of
the two most recent quarter-end balances of Segment Invested Capital)

(a) Quarterly return is equal to non-GAAP net income of $120 million
plus net interest expense after tax of $10 million for Q2'15, net income
of $133 million plus net interest expense after tax of zero for Q2'14
and $96 million plus net interest expense after tax of $9 million for
Q1'15. Please see "Non-GAAP Net Income and Diluted EPS Reconciliations"
for a reconciliation of non-GAAP net income to GAAP net income.

Return on Invested Capital (ROIC) is a non-GAAP measure that management
believes provides useful supplemental information for management and the
investor. ROIC is a tool by which we track how much value we are
creating for our shareholders. Management uses ROIC as a performance
measure for our businesses, and our senior managers' compensation is
linked to ROIC improvements as well as other performance criteria. We
believe that ROIC provides our management with a means to analyze and
improve their business, measuring segment profitability in relation to
net asset investments. We acknowledge that ROIC may not be calculated
the same way by every company.

Readers are reminded that non-GAAP numbers are merely a supplement to,
and not a replacement for, GAAP financial measures. They should be read
in conjunction with the GAAP financial measures. It should be noted as
well that our non-GAAP information may be different from the non-GAAP
information provided by other companies.

The preliminary reconciliation of ROIC is based on our current
information.
